Good Evening EPDM Developers!


Good Evening EPDM Developers!

Today is November 13, 2012 and its about 11pm. Had a fantastic day today because I worked from the home office and got to take my daughters to school.

Today I spent the day coding a small vb.net addin which hooks a data card button. Here’s a screen capture of the data card editor. The image is out of whack a bit and I was hoping it would be like the ones on SolidWorks forums that shows a thumbnail but when clicked zooms to original. Can’t argue with FREE! 🙂


It is kinda cute, the source file has a datacard button that pops up a browseforfile box, user selects a destination file, and the addin grabs the document number, description, and revision from the drawing selected and adds the values to the data card the button was executed from. Not too bad.

There isn’t a lot of additional error handling built in as this is just getting the prototype into demo mode.

Decided to test my boundaries a bit because operations needs the ability to reference the two files easily so….I also AddFileShared into the destination folder. Tomorrow I plan to add more code to paste a reference just for grins.

Oh, forgot to mention the button also works on a template card while the template is running. That was a minor challenge hooking the interface to populate the variables since there isn’t too much documentation on how this is done in vb.net.

Here’s the source code. Enjoy!
